Why does a cat cough when it purrs? - briefly

Cats may cough while purring due to an underlying respiratory issue or irritation in their throat. This is often associated with conditions like asthma, allergies, or hairballs. If the coughing persists, it's advisable to consult a veterinarian for proper diagnosis and treatment.

Why does a cat cough when it purrs? - in detail

Cats are fascinating creatures, and their unique behaviors often leave us with questions about their health and well-being. One such behavior is the occasional cough that can occur during purring. To understand why this happens, let's delve into the physiology of cats and the mechanisms behind these seemingly contradictory actions.

Purring in cats is a complex process that involves the larynx (voice box) and the diaphragm. The vibrations produced by the laryngeal muscles as air passes over them create the distinctive purring sound. This action requires precise coordination between the nervous system, respiratory tract, and vocal cords.

A cough, on the other hand, is a reflexive response to irritation or obstruction in the respiratory tract. When a cat coughs, it forcefully expels air from the lungs to clear any blockages or irritants. This action involves rapid contractions of the muscles in the chest and abdomen, which can momentarily disrupt the smooth rhythm of purring.

The coupling of these two behaviors—purring and coughing—can occur for several reasons:

  1. Respiratory Irritation: Cats may experience temporary respiratory irritations due to dust, allergens, or minor infections. These irritants can trigger a cough reflex while the cat is purring, leading to a sudden disruption in the purring sound.

  2. Asthma and Bronchial Issues: Some cats suffer from feline asthma or bronchial issues, which can cause inflammation and narrowing of the airways. During purring, the increased respiratory effort may exacerbate these conditions, leading to coughing episodes.

  3. Foreign Bodies: Occasionally, cats may inhale foreign objects such as grass blades or small particles, which can lodge in their respiratory tract and cause coughing during purring.

  4. Neurological Coordination: The neurological pathways that control purring and coughing are intricately connected. Sometimes, the reflexive action of coughing may temporarily override the purring mechanism, resulting in a brief interruption of the smooth purring sound.

  5. Emotional States: Cats can exhibit a range of emotional states through their vocalizations. A sudden change in emotional state from contentment (purring) to stress or discomfort (coughing) might cause this overlap in behaviors.

While occasional coughs during purring are generally not a cause for concern, it is essential to monitor your cat's overall respiratory health. If the coughing becomes frequent or is accompanied by other symptoms such as difficulty breathing, wheezing, or lethargy, it is advisable to consult with a veterinarian. Regular check-ups and proper care can help ensure that your feline friend remains healthy and happy.
